Inconsistent table borders with FireFox

Question

I have some tables which render fine in IE and Chrome. But in Firefox some of the border arbitrarily don\'t show or have different widths. You can see an example Here. Below

Answer 1

border-collapse:separate;

I know it's not the direct answer, but the search brought me here.
